Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of PCT/KR2009/002318
filed on Apr. 30, 2009 which claims the benefit of Korean
Application No. 10-2009-0027548 filed on Mar. 31, 2009, the entire
contents of which are incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention relates, in general, to a dome type
security camera structure with a reinforced waterproofing function
and, more particularly, to a dome type security camera structure
with a reinforced waterproofing function which is constructed to
drain moisture, such as rainwater, that enters the camera structure
through a housing, between the housing and a mounting bracket.
BACKGROUND ART
[0003] Generally, dome type security cameras are often installed in
interiors and outdoors, such as in outdoor parking lots or on the
outer walls of a building, for the purpose of security.
[0004] As shown in FIG. 1, the dome type security camera usually
includes a housing 10, a guide member 20, a module holder 30, a
camera module 40, and a dome screen 50. The housing 10 is mounted
to an outer wall or a support 2000. The guide member 20 is coupled
to the bottom of the housing 10 by a plurality of guide protrusions
11 which protrude therefrom. The module holder 30 is hinged to the
guide member 20 in such a way as to move up and down. The camera
module 40 is coupled to the module holder 30 so that its angle of
rotation can be adjusted. The dome screen 50 is detachably mounted
to the housing 10 in such a way as to surround the camera module
40.
[0005] Particularly, mounting holes 13 for mounting the housing 10
to the outer wall of the building or the like, an external power
connection hole 12, and holes for mounting other components are
formed in the housing 10.
[0006] However, the conventional dome type security camera has the
following problems.
[0007] 1) Since we have the mounting hole for mounting the housing
to the outside, the external power connection hole, and the holes
for mounting other components, moisture or rainwater may enter from
the outside through these holes and into the camera.
[0008] 2) Particularly, the rainwater entering the camera space as
such may affect internal components, thus causing damage to the
external power or the camera module.
SUMMARY OF THE DISCLOSURE
[0009] Accordingly, the present invention has been made keeping in
mind the above problems occurring in the prior art, and an object
of the present invention is to provide a dome type security camera
structure with a reinforced waterproofing function, which is
constructed to guide rainwater entering into a housing along a
bracket supporting a camera module to the edge of the housing, thus
discharging the rainwater to the outside.
[0010] In order to accomplish the above object, the present
invention provides a dome type security camera structure with a
reinforced waterproofing function, including a housing 100 having
an outside wire insert hole 110, and a pair of opposite guide
grooves 120 provided on an inner surface of a sidewall of the
housing, each of the guide grooves communicating with an outside
via a discharge hole 130; a mounting bracket 200 which has a
coupling protrusion 210 guided by each of the guide grooves 120,
and is gradually inclined outwards from a center thereof so that an
edge thereof presses a lower surface of the housing and thus the
mounting bracket is coupled to the housing; a holder 300 provided
on a lower surface of the mounting bracket in such a way as to
perform rotation on 2 or 3 axes, with a camera module being mounted
to the holder; and a dome screen 400 mounted to the mounting
bracket 200 and surrounding the holder 300 in such a way as to
adjust a position of the holder in all directions.
[0011] The housing 100 may further include a step 140 so that an
outer edge of an outer circumference thereof surrounds an entire
outer circumference of the mounting bracket 200.
[0012] Further, the guide groove 120 may have on an inner end
thereof a protrusion seat 121 to receive the coupling protrusion
210. The guide groove 120 may be formed such that a depth thereof
is reduced in a direction from an outer position to an inner
position. Contact side surfaces of the guide groove 120 and the
coupling protrusion 210 may be inclined.
[0013] Further, the discharge hole 130 may be formed on the inner
end of the guide groove 120. The discharge hole 130 may be closed
by a lock screw 131. The discharge hole 130 may be formed in the
protrusion seat 121. A lower portion of the protrusion seat 121 may
be formed to be lower than the guide groove 120, thus providing a
step 121a.
[0014] The mounting bracket 200 may have on a central portion
thereof an outside wire mounting hole 220 to be placed on a central
axis of the outside wire insert hole 110, and may be stepped
outward from the outside wire mounting hole 220. A step of the
mounting bracket 200 may be inclined downward in a direction from
an inner position to an outer position. The mounting bracket 200
may be mounted to have a hollow space 230 between the mounting
bracket and an inner surface of the housing 100. Further, the
mounting bracket 200 may further include an airtight sealing member
250' between the mounting bracket and the dome screen 400 to
airtightly seal a gap therebetween.
[0015] The present invention achieves the following effects.
[0016] 1) Since water entering into a housing is guided along the
upper surface of a mounting bracket to the outside of the housing
and is thus discharged to the outside, the function of preventing
the passage of water to an external power and a camera module can
be improved upon.
[0017] 2) Since the operation and maintenance of a security camera
can be easily performed owing to the improved waterproofing
function, cost savings can be expected.

DETAILED DESCRIPTION OF EMBODIMENTS
[0025] Hereinafter, the present invention will be described below
in detail with reference to the accompanying drawings.
[0026] Structure
[0027] FIG. 2 is an exploded perspective view illustrating the
overall construction of a dome type security camera structure with
a reinforced waterproofing function according to the present
invention, FIG. 3 is a sectional view illustrating the dome type
security camera structure with the reinforced waterproofing
function according to the present invention, and FIG. 4 is an
enlarged view illustrating the joint portion shown by the imaginary
line of FIG. 3. Reference numeral "2000" denotes an outer wall or a
support.
[0028] According to the present invention, the dome type security
camera structure includes a housing 100, a mounting bracket 200, a
holder 300, and a dome screen 400. The housing 100 is mounted to
the outer wall of a building or the support 2000. The mounting
bracket 200 is coupled to the lower portion of the housing 100 to
guide water entering into the housing 100 to the outside. The
holder 300 is coupled to the mounting bracket 200 in such a way as
to perform rotation on 2 or 3 axes, and serves to hold a camera
module. These components will be described below in detail.
[0029] FIG. 5 is a perspective view illustrating the construction
of the housing 100 according to the present invention. The housing
100 has the shape of a container with a predetermined thickness. An
outside wire insert hole 110 for supplying external power and
mounting holes 160 for mounting the housing 100 are bored through
the bottom of the housing 100.
[0030] Particularly, a pair of guide grooves 120 each having a
discharge hole 130 is formed in the inner circumference of the
housing 100 in such a way that they face each other. The guide
grooves 120 include insert seats 122, respectively, so that
coupling protrusions 210 which will be described later are
simultaneously fitted into the insert seats.
[0031] In the preferred embodiment of the present invention, each
guide groove 120 may further include a protrusion seat 121 in the
innermost end thereof. Preferably, a step 121a is formed by the
protrusion seat 121 so as to prevent the coupling protrusion 210
from being easily removed from the protrusion seat.
[0032] Further, according to the preferred embodiment of the
present invention, each guide groove 120 may be formed such that
its depth is reduced in a direction from an outer position to an
inner position thereof. The guide grooves formed in this way press
the coupling protrusions 210 when the mounting bracket 200 is
rotated to be coupled to the housing, thus increasing the force of
coupling.
[0033] Moreover, the lower surface of the guide groove 120 which is
in contact with the coupling protrusion 210 may be inclined as
shown in FIG. 4. As such, the inclined lower surface increases the
contact area.
[0034] The discharge hole 130 functions to discharge rainwater
through each guide groove 120 to the outside of the housing 100.
Such a discharge hole 130 is formed on the line extrapolated from
the lower surface of the guide groove 120 or formed on the lower
surface to face downwards, thus allowing rainwater to be easily
discharged. Preferably, the discharge hole 130 is formed in the
protrusion seat 121 so as to prevent rainwater or impurities from
entering the camera structure. More preferably, the discharge hole
130 is closed by a locking means such as a lock screw 131, thus
minimizing the inflow of impurities, in addition to maintaining a
draining function.
[0035] Meanwhile, in order to further enhance the waterproof
effect, as shown in FIG. 4, the housing 100 may further include a
step 140. The step 140 surrounds an end of the mounting bracket 200
that will be described below, thus preventing the mounting bracket
200 from being viewed from the side of the housing 100, therefore
preventing the inflow of impurities or rainwater from the side of
the housing 100.
[0036] As shown in FIGS. 3 and 4, the mounting bracket 200 has the
shape of a disc which has at its center an outside wire mounting
hole 220. Particularly, a stepped coupling part 240 is provided on
the outer circumference of the mounting bracket 200. The bottom of
the coupling part 240 is in contact with the edge of the lower
surface of the housing 100, and the side surface of the coupling
part 240 is higher than the guide groove 120. Further, the coupling
protrusion 210 is provided on the side surface of the coupling part
240 and is guided by the corresponding guide groove 120.
[0037] Preferably, such a mounting bracket 200 is inclined
downwards in a direction from a center to an outer position, thus
allowing rainwater flowing into the housing 100 to collect at the
edge of the housing 100. Further, in order to enable the holder 300
which will be described below to be easily mounted and to make it
easy to utilize space, the mounting bracket 200 may be manufactured
in multiple steps and its height reduced going outwards.
[0038] According to the preferred embodiment of the present
invention, the mounting bracket 200 is formed such that its entire
height is smaller than the internal depth of the housing 100. Thus,
when the mounting bracket 200 is mounted to the housing 100, a
space 230 is preferably formed between the mounting bracket and the
housing. Such a space 230 serves to collect water such as
rainwater, and in addition, serves to arrange the outside wire 1000
for supplying power if the outside wire 1000 should be long.
[0039] The holder 300 functions to mount the camera module which is
usually used for the dome type security camera, and the
construction of the holder remains the same as its general
construction. Such a holder 300 uses a holder which may perform
rotation on 2 or 3 axes in consideration of where it is installed,
a monitoring area, and a photographing angle. Of course, the
rotation of the holder may be performed manually. Further, the
rotating angle of the holder may be adjusted automatically.
[0040] The dome screen 400 serves to capture the image of the
camera module and protect the camera module. The dome screen 400
may be manufactured using common technology. Such a dome screen 400
may be mounted to a mounting protrusion 260 provided on the lower
surface of the mounting bracket 200, by fastening screws 410 into
protrusion insert holes 411. Further, the dome screen 400 may be
fastened to the housing 100 in a threaded manner.
[0041] Mounting Method
[0042] FIGS. 6 and 7 are sectional views illustrating the mounted
state of the dome type security camera structure with the
reinforced waterproofing function of the present invention,
depending on the position of coupling protrusions. Since the method
by which the power supply is connected to the camera module (not
shown) which is mounted to the holder 300 is generally known, a
detailed description will be omitted.
[0043] As shown in FIG. 6, the mounting bracket 200 equipped with
the holder 300 is coupled to the housing 100 mounted to the
outside, such as the outer wall. After each coupling protrusion 210
is fitted into the corresponding insert seat 122, the mounting
bracket 200 is rotated.
[0044] Thereby, as shown in FIG. 7, each coupling protrusion 210
moves along the guide groove 120. The coupling protrusion 210
moving as such is finally seated in the protrusion seat 121.
[0045] When each coupling protrusion 210 is seated on the
corresponding protrusion seat 121 as such, the mounting bracket 200
is further covered by the step 121a. Thus, the coupling protrusion
210 is stopped by the step 121a, thus locking the mounting bracket
200.
[0046] Finally, the dome screen 400 is fastened to the mounting
bracket 200 using a fastening means such as a screw. In this way,
the mounting operation of the dome type security camera structure
with the reinforced waterproofing function according to the present
invention is completed.
[0047] Although the preferred embodiment of the present invention
has been disclosed for illustrative purposes, those skilled in the
art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying
claims.
